Answer:
x=12
Step-by-step explanation:
use midpoint theorem that said that the small line segment (3x+11) is half of the segment ( 9x -14)
2(3x +11) = 9x -14
6x +22 = 9x -14; distribute
6x -9x = -22-14; subtract 9x and 22 from both sides
-3x = -36; divide both sides by -3
x= 12

So hmm check the picture below

a)
well, clearly is 80 ft/s
b)
when t = 1? well 80(1)
c)
in the picture, x-axis is the time and y-axis is the height
so, it reaches its maximum at the vertex, after "x" seconds

so it reached the vertex after

d)
the maximum height of the ball is
